I’ve built Unsearch, a tool that helps you manage your browsing data across different browsers in one place. Some of the main features:

- Sync bookmarks, tabs, and search history from any browser

- Manage, edit, and delete bookmarks and history in the web app (even offline)

- Copy bookmarks between different browsers

- Download your data whenever you want

- Advanced search with exact, fuzzy, and semantic options

It’s fully open-source and currently in alpha, so feel free to check it out.

Looking forward to your feedback!
